Specification of Letters Patent.

Patented Feb. 27, 1906.

Application filed May 20, 1904. Serial No. 208,968.

To all whom it may concern:

Be it known that we, CHARLEs M. EAvEs,

'JoHN W. SLAVEN, and GEORGE.W. WADE,

cart or wagon in advance of the sweeping mechanism as the deviceproceeds.

We are cognizant of the existence of Patent No. 746,229, granted to A.S. Young, December 8, 1903, and herein disclaim any of the specificinventions disclosed by said patent.

Our invention consists in novel structural features and combinations ofparts, the operation of which parts separately and in combination willbe found hereinafter described and the novel combinations of which partsare specified in the claims of this specification.

Mechanism showing the arrangement, connection, and mutual relationshipof the parts forming the subject-matter of our improvements isillustrated in the accompanying drawings, in which- I Figure 1 is anelevation of one side of a sweeper and parts of awagon, and Fig. 2 is anelevation of the opposite side thereof, both embodying our invention.Fig. 3 is a perspective of the rear frame and parts connected thereto.Fig. 4 is a transverse section in the line 4 4 in Fig. 1. Fig. 5 is aside elevation. Fig. 6 is a sectional View.

Referring again'to the drawings, in which like letters or numerals referto like parts in the several figures thereof, 1 represents part of awagon box or body, and 2 the rear supportingwheels thereof, to thespokes 4 of one of which is secured a master-wheel 3 for actuating thesweeping and elevating devices. On the sides and at the upper edges ofthe wagon-body we have provided keepers 5 for purposes hereinafterdescribed. These keepers are preferably of sheet metal .bent intoinverted-U-shaped form and bolted. All the rest of the parts of thewagon may be of any ordinary type of dust-tight dump-wagon and need notbe further described herein. For the purposes of this specification weshall hereinafter term the foregoing parts (1, 2, 3,

4, and 5) the forward section.

, The frame of the rear section, (shown fully at Fig. 3,) which frame isinclosed by a casing and which carries or supports all the operativeparts of the elevator and sweeper, is preferably of angle iron or steel;but we have shown it as of strap metal, and it is constructed asfollows: Beginning at the point X, Fig. 3, one of a pair of bars 6 6 isextended forwardly to a point Y, where it is bent backwardly uponitself. It is then extended backw ardly and rearwardly, thence upwardlyat an angle of about twenty-five degrees, thence downwardly at about thesame angle to the juncture of the drum and chute, (hereinafterdescribed,) thence upwardly and rear wardly, and thence downwardly toits rear end 7, where it is bolted or otherwise fixed to one of a pairof bars or rods 8 8, which extend forwardly to the point 9, is thencebent at an angle corresponding to the parallel bend of the bar 6, thenceupwardly to its point of meeting with the bar 6, to which it is secured.The bars 8 8 are curved or bent at points shown to form parts ofjournalboxes, hereinafter described. 10 10 are trusses; 11 11 and 12 12,braces or stiffeningrods. 13 is a brace rod or plate. 1.4 14 arediagonal rods or braces. 15 15 are rods secured to the upper and lowerframe-bars 6 6 and 8 8, respectively, by bolts or rivets.

Fixed to the bars 8 8.are hangers 1'8 18, which are bent to formjournal-boxes 19 19. 20 20 are rods secured in any preferred manner attheir upper parts to the rods 6 6 and at their lower parts to the rods 88, as shown. 21 21 are bars secured to the bars 6 6 and 8 8 in a similarmanner, but their ends extending in opposite directions from the ends ofthe bars 20 20. The bars 20 20 and 21 21 are secured to each other, andat their submedian portions are bent to form journal-boxes 22 22 for apurpose hereinafter described. 23 is a metal plate connecting rear partsof the bars 6 6. 24 24 are eyes secured to the under sides of the bars 8S. For the purposes of this specification we shall hereinafter designatethe foregoing described parts as the rear frame or frame A.

In mesh with the master-wheel 3 is a pinion 25 on one end of a shaft 26,journaled in suitable bearings 19 in the frame A. On the distal end ofthe shaft 26 is a sprocket-wheel 27. Above and in mesh with the pinionis a spur-wheel 31 on one end. of a shaft 32, j ournaled in suitablebearings 17 in the frame A. On the distal end of the shaft 32 is asprocket-Wheel 18. J ournaled in bearings 16 in the standards B of theframe A is a shaft 30, having a roller 34 fixed thereon. On the distalend of the shaft is a sprocketwheel 29, geared by a sprocket-chain 35 tothe sprocket-wheel 18. Journaled in suitable bearings 22 in the inclinedstandards C v of the frame A is a shaft 36, having fixed thereon aroller 37. v

The main portions of the frame are inclosed within a dust-proof casingD, having a forwardly and upwardly inclined and extended part or chute Eand an enlarged rear part or drum F, as shown best at Figs. 1, 2, and 5.The casing may be of any desired material,- but we prefer that thebottom of the inclined portion E be of boards or other smooth material,so that an endless conveyer 38, having pans or blades 59, which conveyerpasses around the rollers 34 and 37, will not become accidentallyengaged by nor entangled with the frame A.

Exterior to the sides of the drum F and depending from the cross-bar 23are hangers 39, which pass downwardly through guidebrackets 40, securedto the sides of the drum F, and at their lower ends 41* are enlarged toform bearings for the reception of a shaft 41, which carries a broom 42.The upper portions 39 of the hangers 39 are threaded and have nuts 23turned onto them and bear upon the topside of the plate 23, throughwhich said threaded portions of the hangers pass, so that by turning thenuts in one direction or the other the broom-shaft may be raised orlowered, as desired. Any other wellknown means for raising and loweringthe broom may be used, if desired.

To support the rear end of the frame A and the casing D we have providedcaster-wheels 43, secured to the bars 6 of the frame by rods 44 andbraces 45. The wheels 43 are carried by forked stocks 46 the upper partsof which rotate on their axes in bearings in the rear ends of thehangers 44 and braces 45.

In sweepers of the type to which this invention relates it is desirableto use but one rear section with several forward sections and to savetime in connecting and disconnecting them. To effect this object and forthe purpose of connecting the sections rigidly together, we haveprovided draw-bars or connecting-rods 46 46, which are secured by hooks47 at their rear ends to eyebolts 24 in the frame-bars 8, Fig. 3, and attheir forward ends by hooks 48 to eyebolts 49 in the rear axle 50 of thereceiving-wagon. To further effect this object, we have provided legs 5151 for supporting the forward end of the rear section when it isdisconnected from the forward section, which legs are hinged at theirupper portions 52 52 to the frame-bars 8 8 and supported at their freeends when not in use by hooks 53 53. The legs are secured to each otherand made rigid by crossbraces 54 54 and diagonal braces 55 55.

When it is desired to begin sweeping, the forward and rear sections areconnected, as shown at Figs. 1 and 2,with the forward ends of the bars 6of the frame A resting securely in the housings 5 and on the upper edgesof the sides of the wagon-body 1 and the hooks 48 on the connecting-rods46 engaged with the eyebolts 49. The draft-animals being then attachedto the guide-pole, the machine is drawn forwardly and the operation ofsweeping proceeded with in an evident manner. When the receiving-wagonis filled, the dirt having been swept up by the broom 42, deposited onthe conveyer 38, elevated thereby and deposited in the wagon-box, thesupporting-legs 51 are let fall to the position shown by full lines atFig. 3, the hooks 48 are withdrawn from the eyes 49, and the wagon drawnaway for the purpose of unloading or dumping. It will readily be seenthat the legs 51 will then support the part E of the rear section in anormally upright position, ready for engagement with an empty wagon,which may be backed up into place and engaged with the rear section, ashereinbefore described. The legs 51 being then raised to the positionshown by full lines at Figs. 1 and 2, the operation of sweeping, may berecommenced. In operation the draft-animal s are attached to the pole ofthe receiving-wagon and the forward and rear sections connected ashereinbefore described, with the open forward end of the casing or chuteresting over a corresponding opening in the top of the Wagon -box, whichis elsewhere dust-tight and which is preferably a dumping-box. Themaster-wheel fixed to one of the rear wheels of the wagon will berotated thereby in the same direction, and its rotation will betransmitted to the pinion 25, and thereby to the sprocket-wheel 27 onthe shaft 26, but in a reversed direction. A sprocket-chain 56 passesaround the wheel 27 and also around a sprocket-wheel 57 on the distalend of the broom-shaft 41. With this arrangement the rotation of thewheel 27 will be transmitted to the wheel 57 and to the broom-shaft 41and broom 42 and in the same direction, or, in other words, the broomwill be caused to revolve in a direction opposite to that of theground-wheel of the wagon. The pinion 25, being meshed with thespur-wheel 31, will transmit movement thereto, but in an oppositedirection. The wheel 31, being fixed on the shaft 32, will transmit thesame motion to the s rocket-wheel on the distal end thereof, and saidwheel being. geared by the sprocket-chain 35 to the sprocket-wheel 29 onthe roller-shaft 30 will transmit its motion IIO thereto and in the samedirection. per portion of the endless conveyer 38, passing over thefriction-roller 34 on said shaft and the lower portion thereof passingaround the roller 37, it will be revolved in the direction of the arrowsby its frictional contact with the roller 34. That part of the broomwhich is in contact with the surface being swept revolving forwardlythrows the dust and dirt ahead of it and onto the pans 59 on the endlesscarrier 38 and carries it upwardly to and over the roller 34, where itis deposited in the receiving-wagon The carrier-belt being entirelywithin the casing, no dust can dribble or escape therefrom to causeannoyance to persons or damage to property. No gear or operating partbeing within the wagon-box, clogging by reason of dust collectingthereon cannot result. A door (not shown) is provided to close theopening in the top of the box when the wagon is disconnected from therear section.

Shifting boxes may, if preferred, be used for the shaft 36, so that asthe broom wears off in use said shaft may be adjusted rearward intoproper relation to the broom.

The frame, the casing, and all the operating parts being supported attheir forward parts by the wagon, which preferably is constructedwithout a reach, and the rear portions supported by the caster-wheels,great facility and ease of operation is attained, and the constructionpermits of turning the device in a space not greater in diameter thanits own length.

The advantages of the operation will be apparent, and the operation willbe understood from the foregoing description, it being particularlynoted that various changes may be made in the details of constructionwithout departing mater ally from the general idea involved.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is
